New-Generation Anchors: Why Choosing the Right Size Anchor Matters
New-generation anchors are highly popular among boaters for their deep-setting capabilities and reliable holding power. However, choosing the correct anchor size is crucial for optimal performance and safety. Contrary to common belief, a bigger anchor is not always better.
The holding power of an anchor depends on how deeply it sets into the seabed, which is influenced by engine power and vessel windage—not just anchor weight. For example, a well-set 15kg anchor may develop a 300kg hold, while a larger 20kg anchor under the same conditions might set more shallowly and provide similar holding power.
Using an anchor that is too large for your boat can cause several issues:
-
Unburied shanks reduce resistance to yawing and can decrease holding reliability.
-
The anchor may trip easily if the chain slips under the shank during light winds.
-
Partial fluke burial lowers holding power and prevents the anchor from achieving its designed pull angle.
-
Larger anchors put unnecessary strain on the windlass, bow roller, and pulpit fittings.
-
Oversized anchors can affect vessel maneuverability and increase the risk of dragging.
Proper anchor sizing improves safety, maneuverability, and ease of handling, especially for solo sailors or those with smaller crews. Oversizing adds inconvenience, risks equipment damage, and offers no guaranteed holding improvement.
Follow manufacturer anchor size recommendations to ensure your anchor performs effectively, keeping your boat safe and secure in all conditions.
